TO ALL WHOM IT MAY OONCERN:

Be it known that I, MAflHIAS SPENLE, of Detroit, in the county of Wayne, and State of Michigan, have invented a new and improvedY Machine for Finishing Lasts; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same; reforence being had to the accompanying drawing, forming part of this speciiication, in which'- Figure l represents a longitudinal vertical section of this invention, the line xx, g. 2, indicating the plane of section.

Figure 2 is a plan or top view of the same.

Similar letters of reference indicate corresponding parts.

This invention relates .to a machine which is intended to finish the toes and heels of lasts, as the same'are received from the last-turning machine. It consists of a vibrating head containing two adjustable clamps, which are connected together and one of which is intended to receive the pattern last, while the other receives the last to be nished. This head stands opposite to adouble spindle-stock, one part of which carries the guidewheel and the other the cutter-wheel. As the pattern last is pressed up against the guide-wheel, the cutters act on the last to be finished and the toe and heel of this'last are worked down inexact conformity with the pattern last.

A. represents a frame, made of iron or any other suitable material. From this frame rise two lugs, a, which form the bearings for the gudgeons, 6, on which the head, B, swings and this head forms the bearings for the g'udgeons, c, of a platform, C. To this platform are attached, by pivots 0l, two clamps, D D, which are connected by a link e, so that if vone of the clamps is made to turn or swing on its pivot the other is compelled to follow. The clamp, D, which is to contain the last to be nished, is provided with an adjustable stop or abutmentf, whereby said last can be readily adjusted in the required position. The pattern last, as well as the last to be nished, is retained in the desired position by suitable clamping-levers and screws or any other convenient means. Opposite the swinging head, B, are twospindle-stoeks, E E, firmly attachedto the frame A, and placed side by side, as shown in fig. 2 of the drawing. One of these spindle-stocks contains the guide-wheel F, and the other the cutter-wheel G, to which a quick revolvingl motion is imparted by a belt running over a pulley H or in any other suitable manner. After the pattern last has been properly adjusted in the clamp D, the last to be finished is secured in the clamp D, and by keeping-the toe part of the pattern last in contact with the guidewheel, the toe part of the last in the clamp, D', is finished, and, in the same manner, the heel is brought down to the desired shape. By this arrangement the toes and heels of all lasts of the same size become uniform, and the operation of finishing said lasts can be performed with great ease and without requiring particular skill or attention.

What I claim as new, and desire to secure by Letters Patent, is-

1. The arrangement of two clamps which are coupled together, one to contain the pattern last, and the other the last to be finished, in combination with the guide-wheel F, and cutter-wheel G, constructed andoperating substantially as and for the purpose described.

2. The swinging head B, and adjustable platform C, carrying the clamps D D', in combination with the guide-wheel and the cutter-wheel, substantially as and for the purpose set fort The above specification of my invention signed by me this Ist day of October, 1866.
